What Is Coin Control in Bitcoin Wallets and Why It Matters for Privacy
When you use a Bitcoin wallet, it might feel like sending money is as simple as choosing an amount. But under the hood, Bitcoin uses something called UTXOs — and how you spend them can reveal more about you than you think.
This is where coin control comes in. At wmiran.com, we believe privacy and control go hand in hand. This guide will show you how coin control works, and why it’s essential if you care about Bitcoin privacy and transaction efficiency.
What Is Coin Control?
Coin control is a wallet feature that lets you manually choose which UTXOs (unspent outputs) to spend in a Bitcoin transaction.
Instead of letting your wallet automatically pick coins — which can create privacy leaks — coin control puts you in charge of exactly which inputs are used.
Why Does It Matter?
- Privacy: Avoid linking unrelated addresses together by choosing specific UTXOs
- Fee savings: Spend smaller UTXOs when fees are low, larger ones when they’re high
- Labeling: Track where funds came from (e.g., mining, swaps, donations)
- Avoid dust: Prevent the wallet from using tiny, unspendable outputs
How Coin Control Works
- You open your wallet’s coin control section
- You see a list of UTXOs, with their amounts and addresses
- You sеlect the exact coins you want to use in the transaction
- You proceed with creating and sending the transaction
Some wallets also let you freeze certain coins, label them, or sort them by date or origin.
Which Wallets Support Coin Control?
Advanced wallets like the following offer full coin control features:
- Sparrow Wallet
- Bitcoin Core
- Electrum
- Wasabi Wallet (focus on privacy)
